Abrasive flow machining can improve surfaces in complex valves, manifolds, fittings, and precision components where conventional polishing tools may not have adequate access.
For semiconductor fabrication and related high-technology manufacturing, this can provide a valuable finishing step for ultrapure flow components.
Semiconductor Fabrication Depends on Precision Flow Systems
Process equipment used in semiconductor manufacturing relies on carefully controlled gases and liquids.
The metal components carrying those materials may contain very small and complex internal passages.
Even precisely machined components can contain microscopic surface features such as:
- Burrs
- Tool marks
- Surface peaks and valleys
- Small cavities
- Rough intersections
- Uneven internal transitions
AFM for Internal Semiconductor Components
Abrasive flow machining uses a viscoelastic polymer carrying abrasive particles.
The media is forced through selected component passages.
Because it conforms to the geometry, it can reach internal surfaces that may be inaccessible to a rigid polishing tool.
Applications may include:
- Gas-delivery components
- High-purity fluid components
- Precision valves
- Manifolds
- Fittings
- Cross-drilled passages
- Internal channels
- Other process-equipment components
Bay Area Semiconductor Manufacturing
The Bay Area and Silicon Valley have a long history in semiconductor technology, electronics, equipment development, research, and advanced manufacturing.
Suppliers within this ecosystem often work with precision components where small surface defects matter.
AFM can help address the internal finishing challenge without requiring manufacturers to simplify component geometry for tool access.
That is particularly useful for compact components where function depends on intricate internal pathways.
Surface Finish and Cleanliness
A smoother internal surface has fewer pronounced peaks and valleys than a rough-machined one.
For high-purity systems, reducing these features may help minimize areas where unwanted material can collect.
Extrude Hone AFM's general surface-finishing data lists improvements such as approximately 16–18 Ra to 3–4 Ra and 32 Ra to 8 Ra or better.The achievable finish varies according to the component.
AFM improves the manufactured metal surface but does not replace semiconductor-industry cleaning, cleanroom, inspection, or qualification procedures.
Deburring Microscopic Features
Small cross holes and intersecting passages can produce burrs that are difficult to reach conventionally.
AFM flows directly through the feature.
This enables abrasive action to remove protruding material and condition edges in areas hidden from direct view.
For high-purity fluid or gas components, eliminating these internal machining remnants can be an important manufacturing objective.
Selective Finishing Through Tooling
AFM tooling performs three basic functions: holding the workpiece, directing abrasive media toward the surface to be processed, and protecting areas where abrasive flow is unwanted.
That control is particularly useful for sophisticated process components containing multiple functional surfaces.
Materials
Extrude Hone AFM can evaluate components made from titanium, Inconel, superalloys, hardened materials, aluminum, copper, bronze, and other metals.Media selection is matched to the material and desired result.
